Abstract

A method and apparatus for metering and pumping multicomponents of high and low viscosity materials and subsequently mixing and applying such mixture includes gear pumps (62, 64) for pumping each component. Each gear pump has gears (156, 162) operating in a gear housing (66) for receiving and pumping one of the components. The gear pumps are simultaneously driven at a predetermined speed and each gear pump is designed to pump a predetermined amount of its respective components, at the predetermined speed. Flexible hoses (42, 44) connect the pumps (62, 64) to an applicator (44). Check valves (96, 98) are used to maintain the pressure in these hoses when the pumps are in their at-rest position. The gear pumps (62, 64) may be driven at the same rotational speed but are designed to pump a predetermined amount of the different materials so that the ratio of materials can be precisely set.
Where a single fluid is pumped, a gear pump (62′, 62″) is driven by a hydraulically driven torque motor (64′) or an electric motor (70″). The pump has a discharge connected by a hose (40′, 40″) to a dispenser (44′, 44″). A check valve (96′, 96″) is used to maintain the pressure in the hose when the pump is in its at-rest position. The gear pump need only be operated as necessary to maintain pressure in the hose. Precise metering of the fluid pumped is accomplished by controlling the operation of the gear pump.
